DELIVERYMANS CABINET.

Specification of Letters Patent.

Patented Dec. it, 1915.

Application filed September 15, 1914. Serial No. 361,746.

1" 0 aZZ whom it may concern Be it known that I, MACK Lnsrnn, a citizen of the United States, residing at thecity of Tacoma, in the county of Pierce and State of l/Vashington, have invented certain new and useful Improvements in Deliverymens Cabinets, of which the followingis a specifica-tion.

My invention relates to cabinets for de liverymens use, and has for its object to provide a safe and sanitary cabinet for the reception of milk, groceries and other supplies for domesticpurposes.

The invention is illustrated in the accompanying drawing in which Figure 1 is a rear elevation, Fig. 2 is, a side elevation, and Fig. 3 is a front elevation of the invention. Fig. f is a vertical section showing the interior of the cabinet from thefront. Fig. 5 is a vertical section of the cabinet from front to rear showing the interior mechanism for locking the cabinet. Fig. 6 is a partial vertical section showing the interior locking device from the rear, and Fig. 7 is a horizontal cross section and further illustrates the construction of the cabinet and the locking mechanism. Fig. 8 is a full size plan view of the door locking device, and Fig. 9 is a full size elevation of the same looking from the inside of the cabinet toward the front.

Similar characters refer to similar parts in the several views.

My invention consists of a metallic box A, to be galvanized 0r enameled so as to be perfectly sanitary. A door B hinged at C closes the cabinet. The door is kept closed when the cabinet is empty by means of a slotted spring catch D which engages a stud E on the side of the cabinet.

The novel feature of my invention is the self-locking device within the cabinet, which is operated by the weight of the supplies when placed therein and the door is closed by the deliveryman. This self-locking device comprises a loose platform F covering the bottom of the cabinet, one end of which is turned down as shown at G and rests on the bottom of the cabinet. The opposite end is turned upward and tapers to a point as shown at H, and is suspended on a hook I which is brazed on a tubular shaft J. The tubular shaft J is mounted on a stud K at the front side of the cabinet and in a hole in the rear wall of the cabinet and having a brazed collar L against the inner side of the rear wall to hold it in place. The door B has a knob M brazed thereon provided with a notched stud N to extend through a hole in the side rim of the cabinet opening. A flat metallic catch 0 brazed on the tubular shaftv J having a right angle extension to engage the notched stud N, holds the door tightly locked. when the supplies are placed within the cabinet. The weight of the supplies on the platform F pulls down on the hook I by means of the upturned end H and turning the tubular shaft J actuates the catch 0 to engage the notch in the stud N, thus securely locking the door automatically when closed by the deliveryman.

The cabinet is designed to be fastened from the inside to the outside wall of the house. A knob P having a shaft Q, of sufficient length to extend through the wall of the house is inserted from the inside of the house with its end fitted into the rear end of the tubular shaft J. By turning this knob the house-keeper can turn tubular shaft J and throw the catch 0 and unlock the cabinet door. A stud R having an actuating spring S is brazed on the inner side of the door opening, and acts against the door and pushes it open the distance of the slot 03, in the spring catch D. The housekeeper can then go outside and by releasing the spring catch I) open the door B and take the supplies from the cabinet.

It is to be observed a weight arm T is attached to the rear end of the tubular shaft J and so operates as to turn shaft J and lift the platform F and turn catch Q back so as to not engage the notched stud N when the cabinet is empty. The guide piece U limits the swing of the arm T so as to insure the perfect operation of the locking and the urn locking mechanism. The weight arm T being inclosed between the house and the rear wall of the cabinet prevents anyone from meddling with the automatic operation of the lock.

The cabinet is designed to be sanitary. The bottom is slightly inclined to a central hole V for allowing the water to run out when the cabinet is washed. This hole is protected with a shallow cup-shaped shield W with a drain hole to one side so a stick cannot be thrust through V and lift the platform and thus open the cabinet door.

Having thus briefly described my invention, it will be observed the cabinet cannot be securely locked automatically until the house. The drain hole in the bottom admits deliveryman places the i article delivered within the cabinet and its Weight on the platform F operates the locking'mechanism so that when the door is closed by the deliveryman it is locked and can only be opened by the housekeeper turning the knob P Within the house. The cabinet thus constructed With an automatic locking device can be used for delivering milk at night and groceries and other deliveries during the day, and is a safe, useful and convenient article to the housekeeper.

The cabinet may be made of any size desired. It can be perforated for ventilation as cabinets of this kind usually are made.

It can "easily be fitted and attached to the of the cabinet being vvashed on the inside and kept clean and sanitary.

- Having thus described my invention, What I claim as new and desire to secure by Letters Patent is r A dehverymans cabinet comprlsing a '(lopies of this, Patentmay be obtained for suitable box, a door hinged to the box, a notched stud on the inside of the door, a shaft journaled in the box, a latch secured to the shaft and adapted to engage the notch 0f the stud, a platform Within the boX having one end hung from said shaft so as to revolve the shaft when a Weight is placed on the platform, a weighted arm secured to the shaft to normally maintain the same in unlocked position, means for limiting the motion of said arm, manually operable means at the rear of the boX' for revolving the shaft to unlock the latch, a spring for opening the door when unlatched, and means for limiting the distance which the door is opened by the spring.

In testimony whereof I afiix my signature in presence of two Witnesses.

MACK LESTER.
